Hi, I started to program with the SDK last night, and I ran into some
questions.

I use Delphi 4.

1.
in these C++ programs I see things like:

if (rc = aw_init (AW_BUILD)) {
printf ("Unable to initialize API (reason %d)\n", rc); exit (1); }

Am I right in trying to translate this into

rc:=aw_init(AW_BUILD);
if rc=0 then
messages.lines.add('API initialized succesfully') //messages is a
memo box
else
begin
messages.lines.add('Failed to initialize API');
exit;
end;

This seems to work correctly, but I'm not sure. And how can I use the %d?


2.
I tried to make my bot say something with

aw_say('[beep]');

it should have said [beep] but it said nothing.

messages.lines.add("Faied to initialize API reason=%d",rc); <I guess it is still valid in Delphi>

Aren't you supposed to use text quotes? (aw_say("[beep]");) "'" used to quote characters only in "C".

Again I'm not a Delphi expert, but coming from "C" it seems obvious.

is the bot instance created correctly?
is it logged into the universe and logged into any world?
did it announce its position in the world?

There are versions of the Sample Programs in the Delphi threads for 10/1/98 and
10/13/98. They stick as close as possible to the C code of the original Sample
Programs, so that you can easily see what has to be modified to work in Delphi.
Some of your questions will be answered there. Most of the Delphi threads since
that time are clearly labeled; if you want to work with a Delphi encapsulation
of the SDK, see the 2/13/99 thread. For example, in Sample 1, the Greeter Bot
uses aw_say with the string parameter (in single quotes, as usual) converted
from a Delphi string to a C string by a PChar typecast (in the line before the
call to aw_say). The encapsulated versions of the Sample Programs allow you to
ignore details like how and when aw_init is called; it already has a unit
containing resource strings for the reason codes, and to log them to your memo,
all you have to do is to enable the BotMaster object's Reason method and direct
its Reason output to your memo control.
